Title: Production of polylactic acid
Inventor: FUJII YASUHIRO
IPC: C08L67/00
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To obtain a high-molecular weight polylactic acid excellent in heat stability and having a form suitable for molding by adding a phosphoric or phosphorous compound when polymerization sufficiently proceeds in a process for producing a polylactic acid through ring-opening polymerization from lactide serving as the main raw material. SOLUTION: A main raw material comprising lactide, mixed with a catalyst comprising, e.g. a tin compound in an amount of 0.001-0.1wt.% based on lactide, is thermally polymerized at 120-180 deg.C for 1.0-30hr to give a polylactic acid with an average molecular weight of 5 to 300,000. When the molecular weight becomes at least 50,000 in the polymerization, a phosphoric or phosphorous compound is added in an amount sufficient to provide a molar ratio of this compound to the catalyst of (0.5 to 20):1 to inactivate the polymerization catalyst, thus giving a polylactic acid excellent in heat stability. The obtained polylactic acid is formed into granules or pellets for use as a molding material, or formed into film or fibers for use, e.g. in medical applications or as a biodegradable plastic.

Title: Motion control device for vehicle
Inventor: MATSUMOTO SHINJI
IPC: B62D105/00
Filed: 1992-07-16
Abstract: PURPOSE:To control the motion of a vehicle by using 4WS and braking force control and perform effective, efficient and optimum control sharing of each system in response to lateral G and/or longitudinal G in use. CONSTITUTION:A device depends on a yaw rate F/B for rear wheel auxiliary steering control and right and left braking force difference control (S110-130). If a lateral G (Yg) is a parameter, the control sharing rate alpha of both controls is determined according to the detected lateral G (S115). The property of the sharing rate is specified to increase each sharing rate in an effective area for both controls. In a low lateral G area, steering angle control which has great effect in such an area is mainly executed, and along with a large non-linear lateral G area the behavior control of the vehicle is mainly changed into right and left braking force difference control which has effect even in such an area. The total effect of behavior control on the vehicle can be improved.

Title: Automatic steering system for vehicle
Inventor: SAKAI KATSUHIRO
IPC: B62D5/04
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To prevent a vehicle from being slipped off from a correct moving locus by judging the propriety of a rotating state of wheels on the basis of a result of the detection by a detecting means, and controlling the driving of a steering actuator on the basis of a result of the judgement. SOLUTION: The angles of rotation are respectively detected by angle of rotation detecting means for front wheel and rear wheel (S1-4). When the abnormality is found in a rate of change of the rotation (S5-8), it is informed to a driver (S9). When an abnormal state is serious (S10), the automatic steering control is stopped (S11), and when the abnormal state is not serious (S14), it is continuously executed. In a normal case (S5-8), the rotating states are compared (S12). When the abnormality is found (S13), the warning is generated (S9), the automatic steering is stopped (S11) when the abnormality is serious (S10), and is continued (S13) when the abnormality is not serious.  That is, as the locking or idling of the wheels during the automatic steering control is informed to the driver, and further the automatic steering control is stopped, the slipping-off of the wheels from the correct moving locus can be prevented in advance.

Title: Selective radio call receiver
Inventor: MAKINO TETSUYA
IPC: H04W88/02
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To surely activate a reporting operation while switch interruption is neglected at the time of reporting by neglecting the switch interruption at the time of shifting to a reporting job. SOLUTION: For time setting, by the entrance of interruption by the pressing of a switch 14 into a CPU 6, the interruption is analyzed by a software inside a P-ROM 4 and increment for an amt. equivalent to a present job is performed. Also, shifting to reporting after receiving a message is performed forcibly even during some kind of setting is being performed. In this case, when the message is received while the switch 14 is continuously depressed and the increment operation is continued (shifting to the reporting operation is forcibly performed), an interruption becomes effective if the user does not stop the depressing of the switch 14. At the time the interruption by the switch 14 is neglected for X sec after shifting to the reporting operation.  Thus, the manual reset of the reporting operation is not instantaneously performed and the reporting operation is surely performed for X sec.
